Growth of the Body and the Brain. The physical growth of the human body increases in a roughly linear manner from birth through adolescence. In contrast, the brain’s physical growth follows a different pattern. The most rapid rate of growth takes place in utero, and from birth to age four the brain grows explosively. The brain of the four-year-old is 90 percent adult size! A majority of the physical growth of the brain’s key neural networks takes place during this time. It is a time of great malleability and vulnerability as experiences are actively shaping the organizing brain. This is a time of great opportunity for the developing child: safe, predictable, nurturing and repetitive experiences can help express a full range of genetic potentials. Unfortunately, however, it is also when the organizing brain is most vulnerable to the destructive impact of threat, neglect and trauma. However, this early pattern of brain growth does not mean that development or organization of the brain is finished.
